Double Glazed Windows Repairs

There are a variety of reasons your double-glazed windows could need repairs, from condensation between panes to dropping or sagging frames. Fortunately, a majority of these issues can be resolved.

If your window or door is difficult to open, consider oiling the hinges, the mechanism and handles. This is a quick and inexpensive solution.

Broken Panes

When a window pane breaks it loses its insulation properties and may cause a draft. If the dividing muntins are broken, it could cause moisture to leak between the glass panes, resulting in condensation, mold and mildew and making your home less energy efficient. It is recommended to have a professional repair a broken window in order to get the best seal and energy efficiency.

First, you'll need to get rid of any broken glass. Begin by placing a protective drop cloth beneath the broken window and then scoring around the perimeter of the pane with an inexpensive glass cutter (available in most hardware stores). Before you begin, grease the cutter of this tool with a light oil. This will prevent the glass from breaking too easily. You can then use the tool's ball-shaped end to loosen the pieces, which should come away quickly.

After the glass has been removed, scrape off any glazing compound that is old from the recess area of the frame. This will reveal the glazier's points and the metal clips that hold the pane in the frame. Replace them if you notice any corrosion. If the window is made of wood the glazier points may be reused if they're still in good condition.

The remaining frame will need to be prepared to allow reflazing. Apply a continuous strip compound to the recess with a caulking tool. Use a high-quality putty like glazier's compound that is available in a cartridge or a conventional compound sold in a can. Let it dry before installing the glass. If the frame has metal clippings, these should be removed as well. Install the dividers.

Condensation

Condensation is one of the most common issues that double-glazed windows may experience particularly in wintertime. It is typically caused by too many levels of moisture within your home. Warm air is absorbed by cold glass and condenses into droplets of water. They then settle in the corners and frame of the window. This can be prevented by opening windows more frequently and improving ventilation by installing extractor fans, and using dehumidifiers to reduce moisture levels. If condensation continues to occur you should contact a professional who can diagnose the issue and fix or replace the windows if needed.

Condensation on a double-glazed glass window is a sign that the seal has failed. The vacuum seal applied at the factory may wear away over time and let cool air get between the panes. This could cause the window doctor to fog up and then develop mold if it is not addressed immediately.

As a quick fix for condensation, you could try using a hairdryer to dry up the excess moisture. This is a temporary fix and should be used only as a final option. If the condensation is allowed to sit for too long, you might be facing mould or dampness in your home, which must be addressed by a specialist.

Professionals can reseal your double-glazed window for a better, more durable solution. They'll remove the damaged glass pane and clean the gap. They will then pipe hot air into the area to dry out any moisture. During the process, they'll also check for any damages or growth of mould, mildew or mildew and apply a draught proofing treatment to ensure that your windows are fully functional and energy-efficient once again.

Draughts

Rubber seals may get worn out in time and create a draft between your two panes. It's a simple fix to replace the gaskets, that will form an airtight seal. This will keep warm air in your home and the colder air outside, saving you money on your energy bills.

Double glazing that is misted could be an indication of blown seals. The unit is comprised of two panes of argon-filled glass separated by a spacer to form an airtight window. If the seal has been blown the water vapour will get into your space through the gap. This can result in condensation between the glass panes that is not able to be removed.

Fortunately it is a simple problem to fix, and the windows can be replaced quickly by experts who have all the right tools and know how to do it properly. The specialist will use tools designed to push the new seals in place and is generally faster than doing it manually. The tools also come with a pointed end which is useful for pushing the seals into the corners.

In certain situations, a professional may be able to 'reseal your windows' by drilling a small opening into the window and then putting in an adsorbent material or putty. This is less expensive than replacing your double-glazed windows and will still provide you with an effective draught proofing system.

Faulty Hinges

Misted double glazing is a typical problem that many people encounter. It could be caused by a broken seal or crack in the glass, or an issue with the frame or mechanism. It is possible to correct this issue. Typically, this is done by making a new seal between the two glass panes. The new seal will prevent condensation, draughts and leaks.

If you discover any issues, you must contact the company that sold you the windows. You should notify the company in writing and ask for confirmation that they received your notification. Having everything in written form will be helpful later if any disputes arise, because it will be easier to prove that you actually complained.

A window repair expert could drill a hole between your windows in order to eliminate moisture and form the seal. However, this is generally only temporary and won't stop the return of moisture. It is also possible to replace only the glass unit, which will make it watertight.

Be aware that you should only attempt DIY fixes with the knowledge and skills you have are sufficient. Using super glue or another kind of DIY solution can cause more damage in the long run. It is always best to seek professional help if you are unsure what to do.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double-glazed windows in place. There are a variety of reasons that can cause them to break, including age, weather conditions and power washing. It's essential to be aware of what signs are and how to repair them.

When a Window doctor seal breaks it allows humidity to get into the two glass panes and create fog. This is a common issue, and it can cause the window to look visually disoriented. When the seal is damaged, argon and other inert gases are removed from the window, decreasing the glass's insulation properties.

A professional glazier can repair a damaged window seal with a brand new one. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging services that involve putting an air pump inside the window frame to remove the moisture, leaving the glass clear. However, this method is not foolproof and doesn't replace any inert gas, and the fog could come back.

If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is usually the most cost-effective solution and could be a good option in the event you're seeking a long-term solution. But, it's best to choose a firm that has a warranty on replacement windows to ensure that any problems are covered. This way, you can rest sure that you'll get most value from your investment. You can also avoid the problem by selecting the best quality product and following the care guidelines provided by the manufacturer. This will help to prolong the lifespan of your window and decrease the need for repairs.
